ABSTRACT

There were studied 80 patients who were scheduled for cardiovascular surgery and required cardiopulmonary derivation. The were performed magnesium seric determinations three times on each one of them, the firstone as basal sample before getting to the surgery room, the second one during the cardiopulmonar derivation and the last one when they left the surgery room. The purpose was to observe the variations that can happen during the perioperative and the electrocardiography and hemodynamic complications that result from the various determinations. The result will be known at the end of the surgery for not to modify the transanesthetic handling. The performed surgeries were: 16 of valve mitral, 21 for valve aortic, 19 of bypass coronary, 7 of valves tricuspid, 13 combined surgeries and 4 congenital heart disease 1 Jatene, 1 Fontan and 2 interear communication (CIA). The Result: Was obtained from the first basal sample was p = 0.002954, from the second sample was p = 0.00014 and from the final sample was p = 0.237423. These results gives us a significative value, by the test of Mann-Whitney of 0.000061 and by the test of ANOVA for treatments of 0.000020, being statistically significant. Conclusion: A last of magnesium exists during the transurgery that produce hypomagnesemia that is greater after the cardiopulmonary derivation and this causes heart arrhythmias and hemodynamics instability.
